1. A wavelength-division-multiplexing (WDM) system including:

  • a first multiplexer, operatively interconnecting a plurality of digital information channels onto a transmission path;

    a transmission path including an optical fiber span whose length (L) exceeds 10 kilometers and whose zero dispersion wavelength (λ

    0) is about 1310 nm, CHARACTERIZED IN THAT the optical fiber has a loss at 1385 nm, which is less than its loss at 1310 nm, and a chromatic dispersion of between 1.5 and 8.0 ps/nm-km in the 1.4 μ

    m wavelength region; and

    wherein the first multiplexer provides at least three channels of WDM signals in the 1.4 μ

    m wavelength region onto the transmission path.
